A fast ball is when the pitchers throws the ball straight at the strike zone, it doesn't curve (curve ball) or lower (slider), it goes straight ahead.
One is thrown slow and the other is thrown fast.

'Change up' is another name for a 'slow ball'. Where a fast ball may be thrown around 90 or so MPH, a change up would be thrown in the 75-80 MPH range. It is thrown with the same motion as a fast ball and is used to fool the batter into swinging early at the pitch.
Yes, the curve ball curves. This is because of the way the ball is thrown, which is a kind of a spin/jerky fast motion.

Speed doesn't matter for fast balls, what matters is if it's going straight or not.

Yes, but one thing that you would have to take into consideration is how much the ball hooks in the last 12-20 feet of the lane, or the part of the lane that oil is not placed on. A slowly thrown ball that looks like it is hooking good for the first 40-45 feet will hook more once it gets to the section of the lane that doesn't have oil on it. A faster thrown ball does not have to worry about an extreme hook of the ball at the backend of the lane like a slower thrown ball does.
I was capturing a Ferroseed in Chargestone Cabve and I used an Ultra Ball, it sounded like it was thrown very fast, the ball shook in the air and the Ferroseed was caught without the ball shaking on the ground - why?
A line drive is a ball hit really hard and fast in a straight line.
